IWRG (Grupo Internacional Revolucion) is a promotion based in Naucalpan. They're an independent group with their own championships and television show. IWRG was started in 1996 and was founded by Adolfo Moreno. His three sons have took over management of the promotion before Moreno's death.

Arena Naucalpan was a UWA allied arena to start. It started using both UWA and CMLL allied luchadors for it's top matches in the early 90s, and then switched over to being CMLL only as the UWA failed The two promotions had a falling out in late 2007, over IWRG using El Hijo del Santo. CMLL had banned all affiliated luchadors and promoters from using Santo. IWRG broke that veto, and CMLL refused to send talent any longer.

IWRG went on it's own for a few years, relying on independent luchadors for main event talent while occasionally asking CMLL to repair relations. Finally, in June 2010, IWRG agreed to a deal with AAA. AAA luchadors haven't appeared as much as CMLL ones used to, but AAA has held TV tapings from Arena Naucalpan.

IWRG has also had relationships with Japanese promotions. The first days classes of Toryumon wrestlers got their starts in the early days of IWRG, and are among some of the first champions. IWRG rekindled that relationship with successor promotion Dragon Gate in the late 2000s, to the point of Dragon Gate reps teasing a Dragon Gate Mexico show and CIMA recapturing the IWRG Intercontinental Welterweight Championship, but the promotions suddenly stopped working together. Prior to that, AJPW was sending their rookie wrestlers over to gain seasoning.

IWRG, in good business times, has promoted at other arenas around Mexico State, including Arena Neza and Arena Xochimilco.
